How Is Prostate Cancer Diagnosed? A Step-by-Step Guide

Apr 18, 2025

Early prostate cancer detection is key to treatment. Dr. Samadi explains the diagnosis process, from screenings to biopsy results, for clarity and peace of mind.


Step 1: PSA Blood Test

The first step in detecting prostate cancer often begins with a PSA (Prostate-Specific Antigen) blood test. PSA is a protein made by prostate cells, and higher-than-normal levels may indicate:

  • Prostate cancer

  • Benign prostatic hyperplasia (BPH)

  • Prostatitis (prostate inflammation)

While a high PSA doesn’t always mean cancer, it signals the need for further evaluation.
